Hello guys,
I want your help of advice on a project am working on. It's called the smart blind stick. The thing here is i want to send different audio files with different checks or conditions to a bluetooth headset or any speaker. For example if using the sonar sensor if the object detected is 2500 cm far i want to send an audio file containing the message and if it detects 2000 cm far i want to send a different audio file to the bluetooth headset of cellphone etc. Is this approach possible. I have been searching the internet and youtube for around a week or so but couldn't find optimal help. So, firstly is this approach possible? If yes then what will be the procedure and no what's the alternate way as you have understood my problem that I WANT TO SEND DIFFERENT AUDIO FILES FOR DIFFERENT CONDITIONS. Please help me solving this problem at least i get to know that this is even possible or not. I am a beginner arduino programmer. THANKS
I think this is a non-starter. HC-05 is a plain-vanilla SPP data device. I don't think it will send sound to a bluetooth speaker, although some sort of beep code might work. You need to learn about bluetooth protocols. If you want to send an audio file to a phone, I guess that is easy enough for Arduino and HC-05. All you need do is get the phone app that will play the sound file on receipt.
Thanks a lot for the reply sir. Can you suggest me with any helping material link so i could study about the bluetooth protocols what you may recommend. I would really appreciate that. thanks.
The description implies that it is exactly what you need to send audio to bluetooth speakers. I cannot comment further as I don't know anything about them, but I don't think they will be suitable for anything to do with the phone.
I bet there is stuff on this forum about the XS3868, and you may also find you can get a breakout board similar to that for the HC-05 that will make the module easier to use with Arduino.
